High entropy alloys nanoparticles for unique mechanical properties – YOSEMITE

Submission summary

In recent years, high entropy alloys (HEA) in bulk form have become an exciting field of research in the Material Science community, in particular for their mechanical properties. Due to the high mixing entropy effect, these materials, containing multiple elements (typically 4 to 6), tend to form simple solid solution microstructures. On the other hand, HEA research at the nanoscale is still in its very beginning whereas at this scale remarkable properties have often been demonstrated for pure elements. In the YOSEMITE project, we aim to develop innovative materials based on HEA nanoparticles to achieve original mechanical properties. By combining theory and experiments, we aim to acquire sufficient knowledge about the interplay between the synthesis, the structure (size, shape, composition, order/disorder) and the specific deformation mechanisms of NP-HEAs to reliably guide the engineering of a new class of nanomaterials with unique mechanical properties.
